* Fig. G-is a view-showing thablank from which the end closure-isformed.

Fig. 7 is a fragmentary view illustratingzthe manner of openingthe-container:by tearing out the tear strip.

- Fig. 8 is anenlarged sctional-view on the I indicates the containerbody which may .be

of any suitable material but-which will: prefer- I ably be of glass-or-=-possibly -plasticmaterial.

This container body isshown ashaving; a relatively short neck-portion 2atits-upper;end which provides the opening 3 through which the .con-

tainer is filleda-nd throughwhich-thecentents thereof are discharged.

' The neck 2 is provided at its top-with anexterior bead havinga"cylindrical-side' wall, the under side of. which bead provides adownwardly faoing'shoulder' 4'which is situated a short distance belowthe top of the neck.

The end closure by which the container is sealed is indicated generallyat 5, and it is preferably made of sheet metal. Said end closure isformed with a depending cylindrical skirt portion 6 which encircles andtightly fits the part of the neck above the shoulder 4, the lower edgeof the skirt portion being crimped inwardly beneath the shoulder 4 asshown at I.

In order to provide an hermetic seal for the container, I preferablyemploy a sealing gasket 9 between the top edge of the neck 2 and theclosure member 5, and the central portion of the closure member may bedepressed so as to provide the channel 8 to receive the packing 9, thisand which has itslerigthdimension, that is, the

being a common expedientincontainers of this 'The container .isvconstructed .to,.,be; opened .by tearing out a tear strip..from,the.,end ,closureli, andfor this purpose; the;.skirt,portion'6.o.the end closure is providedwitha.scoreline vi 0. whichextends completely; arqund the skirt at a point slightly abovethe-shoulder 4.

The end closure ,is.;also provided witlra. tab 1 I i which is, formedintegrally. with. the closure dimension fromitstipto its, ,base.-whereit, joins .the skirt ,portion,, ektending parallelto the lower edge oftheskirt, said tabgqbeingspaced,,from

. s lower ed e of th s irtnortion as hown at l2. The end. closure isfurther providedwith a branch scoreline l3 which .ext,ends from theencircling scorelinel0..to,.the,edge of the inturned portion- I.at.a..point. .wh ere the upper edge of the tabmeets, said edge.

The blank fromv which theend closure ismade is shownat 5min Fig.v 5.@Thisyblank-iscircular inshape; and has-the tab. l l...integraltherewith.

The blank is also formed with the circular, scoreline 1 ll ,and'withthe. branch, scoreline. l 3 which extends .from thescoreline l0 to theedgeof the blankat the-point where thetupper edge of the tab meets theedgeef the blank.

After- ;the blank 5a,- has .been .blanked out .from

the" sheet metaland the-tscorelines l0 and I3 have been'formedfin -theblank .then said blank :is deformed by .meanspf dies,:to produce. the

\ end closure such.as;, shown..in. -Fig.. 2. which is provided with thedepending skirtb. The dotted line; Ilin 6;indi cat es;-where; the.blank5a .is.,.=bent to form;.-;the ;skirtpportion ofthe end closure.

The end clos reth s firmed xt e y p d .on the container asvshown inlfig. 3, saidcontainer having previously been provided with the packingmaterial 9, and the end closure is sealed to the container body bycrimping the lower edge of the skirt inwardly beneath the shoulder vlower marginal edge portion of the skirt underneath the shoulder asshown at I but it also bends the root portion l8 of the tab inwardlyunder said shoulder. This crimping operation brings the tab l Iunderneath the shoulder 4 and into a position where it lies flatlyagainst the outside of the container neck 2 and has its lengthdimlinsion extending circumferentially of said neo The encirclingscoreline I0 is situated slightly above the shoulder 4, and the upperportion of the branch scoreline l3 will extend from the scoreline ID tothe shoulder 4 as shown in Fig. 1 while the lower portion of said branchscoreline [3 will be in the portion of the skirt which is crimped inunder the shoulder 4 as shown in Fig. 4.

The advantage of spacing the tab H from the lower edge of the skirtportion as shown at I2 is that said tab will be below and out of .thepath of the crimping wheel which is used for crimping the edge I of theskirt underneath the shoulder 4, and, therefore, said tab will not bedistorted in any way bysaid crimping operation. I

This crimping operation, however, will force the tab into engagementwith the exterior of the neck 2 so that the tab will lie closely againstsaid neck and 'will be situated entirely beneath the shoulder 4. The tabis thereby protected by the shoulder, which is an advantage because iteliminates danger that the tab may he accidentally bent outwardly fromthe position shown in Fig. 4 during the handling or transportation ofthe sealed container.

This tab construction has the further advantage thatit enables thecontainer to be opened by a key element I4 of the usual type which isprovided with a tab-receiving slot l5. To open the container, the freeend of the tab l I will be separated from the neck of the container asshown by dotted lines in Figs. 2 and 4 and then the key M, while held inposition substantially parallel to the container axis, is applied tosaid free" end of the tab and is turned to wind the tab thereon. Whenthetab is completely wound on the key then further turning movement ofthe key will operate to tear the skirt, first along the branch scorelinel3 and then along the circumferential scoreline I0 thereby to tear mifrom will take place along the encircling scoreline l0. Since the tearstrip includes the inwardly crimped edge portion 1 of the skirt 6, saidtear strip will be curved transversely, and as it is wound up on the keyinto the roll Hi, the inner or concave face of the tear strip will bepresented on the outside of the roll and each turn of the roll will thusbe seated in the concave face of the preceding turn.

This is clearly indicated in Fig. 8. The advantage of this is that eachturn of the roll IE will be properly positioned in the roll by thepreceding turn and the roll will be built up on the key without anydanger that the turns of the roll will slip sidewise thus causing acollapse of the roll.

It will be noted that the encircling scoreline I0 is located in thelower portion of the skirt 6. The advantage of this is that, after thetear strip l9 has been torn out for opening the can, the end closurewill still have a skirt of suflicient depth to fit over the top of thecontainer thereby making'it a'replaceable cover or closure.
